DORRESTEIN ADMINISTRATOR OF SAID SAMUEL BENJIMAN ALLI- SON, DECEASED.

FIB ER-SEPARATING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 677,914, dated July 9, 1901;

Application filed May 27,1897. Renewed April 80, 1901; Serial No. 58,219. (No model.)

To aZZ whom it may concern:

Be it known that I, SAMUEL BENJIMAN AL- LISON, a resident of New Orleans, in the parish of Orleans and State of Louisiana, temporarily residing at Guatemala city, Guatemala, have invented certain new and useful Improvements in Fiber-Separating Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same. I

The invention relates to machines for separating and cleaning the fiber of fibrous stalks and leaves; and its object is to provide a simple, economical, and efficient machine that will break the stalks or the like and scutch them and brush them on both sides, the gen eral principles of construction being such as set forth in my Patents Nos. 568,224, 568,225, and 568,309, each dated the 22d day of September, 1896.

The invention consists in the construction hereinafter described and pointed out.

In the accompanying drawing the figure is a partial longitudinal section ofthe stalkbreaking, Wood-separating, and fiber-cleaning parts.

Numeral 1 denotes a frame, which may be of any suitable form.

2 indicates a feeding-table.

3 and 4 denote longitudinally grooved crushing-rollers having diameters of four and a half and three and a half inches, respectively.

5 denotes a hollow receptacle adapted to receive liquid from a pipe (indicated at 6) and distribute it through perforations 7 upon fiber descending between said receptacle and the wheel 8. The receptacle presents a curved face or rubbing-bed 9 to the roller 3 and a similar face or bed 10 to the wheel 8. The Working beds 9 and 10 of theparticular receptacle 5 are not new andare not claimed herein except in the relation hereinafter pointed out. The wheel 8, which has a diameter of thirty-three inches, carries scutchingbars 11 and 'brushes 12 alternately arranged around its whole circumference;

13 denotes a gripping-roller to receive, in

conjunction with roller 4, the fiber partially separated from wood and pass it to and along the face 15 of the block 14. A rotary brush (denoted by 16) is adapted to brush the fiber against the curved face or bed 17 of the block or plate 14. The bristles of this brush are inclined in a direction opposite to that of the rotary movement of the brush to avoid clogging and injury. This supplementary brush acts upon the side of the fiber opposite that cleansed by the brushes carried by wheel 8. It can be adjusted to and from the bed 17 by the screw 18 forcing the bearing 19 against a rubber block 20 and compressing it, as required for the purpose. 21, 22, and 23 respectively denote asimilar screw, bearing, and rubber block for the adjustment of the wheel to or from the bed 10. 24 and 25 denote rollers adapted to move an endless belt 26 to carry off the cleaned fiber.

27 is a roller which cooperates with roller 24 and belt 26 in seizing and bearing away the cleaned fiber as it passes below the bed 17.

28 is a chute to receive the wood and refuse separated from the fiber on bed 10. The refuse removed by rotary brush 16 is swept by it away from the fiber and from the rollers 24 and 25.

The curved arrows denote the direction of rotation of the Wheels and rollers and the straight arrows indicate the direction traveled by the upper and lower parts of the fiberremoving belt.

Thecorrugated rollers break transversely the stalks fed to them across the table and loosen the woodfrom the fiber. The broken wood is still further loosened by the corrugations of roller 3 rubbing the broken stalks on the bed 9 and the soutching-bars and brushes carried by wheel 8 discharge from the fiber the main part of the broken wood and refuse into the chute 28. A final rubbing is effected by the rollers 4 and'lS and 'bed 15, and a final brushing is applied to the fiber on the side opposite that first brushed by the brush 16, working upon the bed 17. The last two operations are deemed important.

In the present improvement in practice the wheel 8 will rotate at the rate of about five hundred turns a minute and the brush 16 will be rotated three times as frequently, or fifteen hundred times a minute.

Having described my invention, what I claim is- 1. The combination of the breaking-rollers 3 and 4, wheel8 carrying wood-separating devices, the working beds 9 and 10, a part 14 provided with beds 15 and 17, the roller 13 cooperating with roller 4 to carry the fiber to bed 15 and a brush 16 cooperating with the bed 17, substantially as described.

2. The combination of stalk-breaking rollers, devices for scutching and brushing the broken stalks, supplementary devices for brushing the opposite side of the fibrous part of said stalks, and intermediate means comprising one of the breaking-rollers and a cooperating roller 13 for transporting the fiber from the scutc'ning and brushing devices to the supplementary brushing devices, substantially as described.

3. The combination of the breaking-rollers 3 and 4: with each other, and beds 9 and 15, the roller 3 cooperating with the bed 9 and the roller 4 with the bed 15, the wheel 8 provided with scutching-bars and brushes, the bed 10, the rotary brush 16, and the bed 17, said wheel carried brushes 12 and rotary brush acting upon opposite sides of the fiber, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

SAMUEL BENJIMAN ALLISON.
